Bruins rookie forward Jakob Forsbacka Karlsson - coaches and teammates identify him by his initials - scored his first career goal 1:12 into the game, and Jake DeBrusk's goal less than two minutes later was all Boston needed for a 2-1 victory over the Arizona Coyotes on Saturday night.

"It's difficult to describe," said Karlsson, who was recalled from Providence of the American Hockey League on Nov. 9.
